Abstract: ABSTRACT      The corner fitting for freight containers, particularly for small and medium-sized containers, as disclosed includes at least three mutually perpendicular walls defining a cube. The outer pyramidal corner region of the cube remote from the container is omitted to form a triangular surface confining the three walls. This oblique triangular surface and at least one of the three walls have at least one opening each for engaging housing and/or coupling elements.     The rear wall of the container fitting may be formed by a triangular junction plate connecting the three corners of the cube walls at their portions diagonally opposite to the removed pyramid, the junction plate extending substantially parallel to the triangular surface of the corner fitting.     The fitting is preferably formed from a blank of circular or semicircular general shape by bending and welding steps in such a manner that two quarter surface portions of the blank overlap each other to form one reinforced fitting wall.

Abstract: ABSTRACT OF THE DISCLOSURE           There is described an improved process for the separation and recovery of L-phenylalanine and L-aspartic acid from sidestreams resulting from the preparation of .alpha.-L-aspartyl-L-phenylalanine methyl ester.  It has been found that superior separation is obtained by combining one or more of the mother liquor and wash solutions formed during the preparation of .alpha.-L-aspartyl-L-phenylalanine methyl ester, hydrolyzing same to afford the hydrohalide salts of L-aspartic acid and L-phenylalanine, acidifying the hydrolysis solution to precipitate the hydrohalide salt of L-phenylalanine, separating the hydrohalide salt of L-phenylalanine, dissolving it in water and adjusting the pH of the solu-tion to the isoelectric point of L-phenylalanine, thus affording pure L-phenylalanine, and thereafter adjusting the pH of the solution after separation of the L-phenyl-alanine hydrohalide to the isoelectric point of L-aspartic acid to precipitate L-aspartic acid.

Abstract: ABSTRACT OF THE DISCLOSURE          A method and apparatus for remotely replacing damaged guideposts attached to a subsea structure are provided.  A receptacle is permanently attached to the subsea structure.  The guidepost is inserted into the receptacle and is releasably connected thereto by one or more radially-oriented, spring loaded lock pins.  Damaged guideposts are removed by applying an upward vertical force to the guidepost sufficient to shear the lock pin or lock pins.  The upward vertical force is applied by a replace-ment tool capable of being remotely operated from the surface of the body of water.  Following removal of the damaged guidepost, a new guidepost is inserted into the receptacle,  Lock pins mounted in the new guidepost retract into the guidepost as it is being inserted.  When fully inserted, the lock pins extend find engage a retaining groove formed in the receptacle thereby firmly locking the new guidepost in place.

Abstract: ABSTRACT OF THE DISCLOSURE         An electromagnetic signal receiver and processor including an IFM receiver connected directly to an antenna for developing frequency data, a pulse status unit also directly connected to the antenna for developing, inter alia, a control signal when the pulse of the received electromagnetic signal exceeds a preselected width, and an IFT receiver which is connected to the antenna through a delay and a blanking network, in that order.  The blanking network is controlled by the control signal, and is unblanked when the pulse width of the received electromagnetic signal is greater than the preselected width to allow the delayed signal to be processed by the IFT receiver.  A memory stores selected frequencies for comparison with the frequency data developed by the IFM receiver.  A further control signal is developed by the network, which compares the output of the IFM receiver and the frequency data stored in memory to control the blanking network.

Abstract: Abstract of the Disclosure An optical waveguide filament comprising a cladding layer, a core and a barrier layer disposed between the core and cladding. The barrier layer comprises silica doped with B2O3, P2O5 and GeO2. The core consists of an inner region and an outer region, the boundary between which is referred to as the core break-point. In the outer region of the core, the concentration of B2O3 de-creases linearly from its barrier layer level to zero at the core break-point, the P2O5 increases at a rapid rate from the barrier layer level to a first concentration level at the core break-point and the GeO2 remains at a constant value between zero and the barrier level. In the outer region of the core, the GeO2 increases from some level up to the barrier layer level to a greater value at the filament axis in a power law fashion. The P2O5 also increases in a power law fashion from the value thereof at the core break-point to a higher value at the filament axis, the increase in concentration of P2O5 in the outer core region increasing at a rate greater than the concentration of P2O5 would increase if the power law P2O5 gradient extended into the outer core region.

Abstract: Abstract of the Disclosure The invention is directed to a container for the long-term storage of radioactive materials such as irradiated nuclear fuel elements.  The container includes a vessel-shaped base body made of a material selected from the group including cast iron and cast steel.  The base body has an outer surface and an opening through which the radioactive materials to be stored therein are passed.  A plurality of ribs made of corrosion-resistant material are formed on the outer surface of the base-body to partition this surface into a plurality of surface segments.  A protective layer covers each of the surface segments to protect the same against corrosion.  A cover is adapted for sealing the opening of the vessel-shaped base body.  The ribs and their arrangement on the surface of the base body of the vessel make it easier to apply the corrosion protective layer and make the layer less sensitive to differential expansion stresses of the contiguous materials.
